I know that qBit has an “excluded file name” option so just add *.exe to it.

I’d leave if I felt some controversy for whatever reason but I currently use multiple instances that I switch between anyway.

Everyday apliances being online is just insane to me.

I’d always recommend not spending any money until you know what you really want and even then use any spares/old stuff you already have. The first build should be a true “budget build” :D
